Describe the issue

I can't seem to find a way to access the queue to resume playback between listening sessions in the Roon ARC Carplay interface. Is there a UI element that I'm not seeing? What I've been needing to do when I get in the car is open Roon ARC on my iPhone to access the queue.

Hi @tretneo,

Thank you for the report. Do you happen to know the original manufacturer of the CarPlay head unit? If this unit came standard with the vehicle, what is the make/year of the car?

Have you enabled voice control in iOS settings for ARC? Sometimes head units will activate safety features once voice control is enabled that remove visual elements from the head unit display; the intent is to minimize browsing while driving. This behavior may change if you disable voice control or put the car in park - I’m curious if either has an effect for you.

We’ll follow up once we see a response. Thank you for the post!

Hi @connor,

This is in a 2024 F-150 so I guess the manufacturer of the CarPlay head unit is Ford.

I don’t believe I’ve enabled voice control in the iOS settings for ARC. I can say that I don’t use Siri to control ARC if that’s what you mean.

I tried it out while driving and while parked but didn’t see a difference in the ARC CarPlay interface either way. Here are some screenshots. As you can see in the iPhone screenshot, I have a song in the queue. But on the ARC interface I can’t see any way to access or resume/play the queue.


Looks like this may be an issue going back to ARC Early Access back in 2022.

Hey @tretneo,

Thanks for the report! Based on your screenshot below:

What happens if you press the resize arrows in the upper left-hand corner? Does that give you the option to resize the carplay screen?

Are you able to check for any software updates to the vehicle/car play?

Hey @benjamin,

The resize arrows in the upper left-hand corner adjusts how much of the Ford Sync screen area is used by CarPlay. What’s actually displayed within the CarPlay interface is unchanged when tapping that button and there is nothing on the Ford Sync side that can be used to interact with the Roon Arc queue.

I checked and the software is up-to-date.

Thanks!
Rob

Hello @tretneo ,

We’ve escalated your case over to our ARC team for review. We’ll reach out again once they’ve finished their analysis of the logging. Thank you in advance for your patience.

Hi @tretneo,

Thanks for your patience so far - we unfortunatly don’t have any updates to share yet, but we have a ticket in with our Arc team for further investigation. Progress is a bit slow, so I apologize for that!

We’ll follow up when the team has more information to share! :pray:

Hi @tretneo,
I just wanted to give you an update on the status of your case. Our QA department is currently trying to find a way to access your queue and queue history without going through Now Playing. I cannot comment on an exact timeline however we will let you know here when we know more.

Thank you for the update, @daniel

Hi @tretneo ,

Just to double-check here, the interface is unchanged whether you have a track playing or not, correct? Having an actively playing track has no change in behavior?

Hi @noris. Actually, the interface works as expected when Roon ARC is or was very recently playing a track. When that’s the case, the CarPlay “Now Playing” icon is visible and accessible in the Roon ARC UI. The issue occurs when Roon ARC either hasn’t been playing recently or some other audio app was most recently in use. In that scenario there is seemingly no way to resume playback or access the queue in the Roon ARC CarPlay UI.

Thanks for the clarity @tretneo - we’ll be back in touch once the team has reviewed further!

Hi @tretneo,

Unfortunately, this is anticipated behavior with most head units - there’s only a small amount of browsing data cached in the OEM head unit itself, mostly as a safety feature.

I recommend creating a Feature Suggestions for this specific behavior where other users can also vote. This will have a broader impact on Product decisions than posting in Support alone. Thanks!
